wx.DateTime¶wx.DateTime class represents an absolute moment in time.
The type DateTime_t is typedefed as unsigned short and is used to contain the number of years, hours, minutes, seconds and milliseconds.
Global constant wx.DefaultDateTime and synonym for it wx.InvalidDateTime are defined. This constant will be different from any valid wx.DateTime object.
Static Functions¶All static functions either set or return the static variables of wx.DateSpan (the country), return the current moment, year, month or number of days in it, or do some general calendar-related actions. Please note that although several function accept an extra Calendar parameter, it is currently ignored as only the Gregorian calendar is supported. Future versions will support other calendars.
Date Formatting and Parsing¶The date formatting and parsing functions convert wx.DateTime objects to and from text. The conversions to text are mostly trivial: you can either do it using the default date and time representations for the current locale ( FormatDate and FormatTime), using the international standard representation defined by ISO 8601 ( FormatISODate, FormatISOTime and FormatISOCombined) or by specifying any format at all and using Format directly. The conversions from text are more interesting, as there are much more possibilities to care about. The simplest cases can be taken care of with ParseFormat which can parse any date in the given (rigid) format. ParseRfc822Date is another function for parsing dates in predefined format – the one of RFC 822 which (still…) defines the format of email messages on the Internet. This format cannot be described with strptime(3)-like format strings used by Format, hence the need for a separate function. But the most interesting functions are ParseTime, ParseDate and ParseDateTime. They try to parse the date and time (or only one of them) in ‘free’ format, i.e. allow them to be specified in any of possible ways. These functions will usually be used to parse the (interactive) user input which is not bound to be in any predefined format. As an example, ParseDate can parse the strings such as “tomorrow”, “March first” and even “next Sunday”. Finally notice that each of the parsing functions is available in several overloads: if the input string is a narrow ( char ) string, then a narrow pointer is returned. If the input string is a wide string, a wide int pointer is returned. Finally, if the input parameter is a String , a narrow int pointer is also returned for backwards compatibility but there is also an additional argument of String.const_iterator type in which, if it is not None, an iterator pointing to the end of the scanned string part is returned.

ConvertYearToBC(year)¶Converts the year in absolute notation (i.e. a number which can be negative, positive or zero) to the year in BC/AD notation.
For the positive years, nothing is done, but the year 0 is year 1 BC and so for other years there is a difference of 1.
This function should be used like this:
dt = wx.DateTimeFromDMY(8, 5, 1977)
y = dt.GetYear()
epoch = (y > 0 and ["AD"] or ["BC"])[0]
print "The year is %d%s"%(wx.DateTime.ConvertYearToBC(y), epoch)

float
GetSecond(self, tz=Local)¶Returns the seconds in the given timezone (local one by default).
tz (wx.DateTime.TimeZone) –
intshort
GetTicks(self)¶Returns the number of seconds since Jan 1, 1970 UTC.
This function is provided solely for interoperability with the standard C library and other libraries using time_t values. If you just need to get the value represented by this object as a number, use GetValue instead, which doesn’t lose precision and covers the entire supported range of dates, unlike this one which is limited to the range of positive 32 bit values, i.e. from Jan 1, 1970 to around Jan 19, 2038 and returns -1 for the dates outside of it.
Additionally, this method must be called on an initialized date object and an assertion failure occurs if it is called on an object for which IsValid is False.

The value returned by this function is the same as the year, except, possibly, for a few days at the very beginning and very end of the year if they belong to a week which is mostly (i.e. at least 4 days) is in another year in which case that other (previous or next) year is returned.
For example, January 1 in 2015 belongs to the first year of 2015, hence GetWeekOfYear for it returns 1 and this function returns 2015. However January 1 in 2016 belongs to the last week of 2015 according to ISO 8601 standard rules and so GetWeekOfYear returns 53 and this function returns 2015, although GetYear returns 2016.
tz (wx.DateTime.TimeZone) –
int
New in version 4.1/wxWidgets-3.1.0.
GetWeekDay(self, *args, **kw)¶ Overloaded Implementations:

flags (NameFlags) – Either Name_Full (default) or Name_Abbr.
string
See also
GetWeekOfMonth(self, flags=Monday_First, tz=Local)¶Returns the ordinal number of the week in the month (in 1-5 range).
As GetWeekOfYear , this function supports both conventions for the week start.
flags (WeekFlags) –
tz (wx.DateTime.TimeZone) –
intshort
GetWeekOfYear(self, flags=Monday_First, tz=Local)¶Returns the number of the week of the year this date is in.
The first week of the year is, according to international standards, the one containing Jan 4 or, equivalently, the first week which has Thursday in this year. Both of these definitions are the same as saying that the first week of the year must contain more than half of its days in this year. Accordingly, the week number will always be in 1-53 range (52 for non-leap years).
The function depends on the week start convention specified by the flags argument but its results for Sunday_First are not well-defined as the ISO definition quoted above applies to the weeks starting on Monday only.

Example:
now = wx.DateTime.Now()
print "Current time in Paris:\t%s\n"%(now.Format("%c", wx.DateTime.CET))
Note

See also
ParseDate(self, date)¶This function is like ParseDateTime , but it only allows the date to be specified.
It is thus less flexible then ParseDateTime , but also has less chances to misinterpret the user input.
See ParseFormat for the description of function parameters and return value.
date (string) –
int
See also
ParseDateTime(self, datetime)¶Parses the string datetime containing the date and time in free format.
This function tries as hard as it can to interpret the given string as date and time. Unlike ParseRfc822Date , it will accept anything that may be accepted and will only reject strings which cannot be parsed in any way at all. Notice that the function will fail if either date or time part is present but not both, use ParseDate or ParseTime to parse strings containing just the date or time component.
See ParseFormat for the description of function parameters and return value.
datetime (string) –
int
ParseFormat(self, *args, **kw)¶ Overloaded Implementations:
ParseFormat (self, date, format, dateDef)
This function parses the string date according to the given format.
The system strptime(3) function is used whenever available, but even if it is not, this function is still implemented, although support for locale-dependent format specifiers such as "%c" , "%x" or "%X" may not be perfect and GNU extensions such as "%z" and "%Z" are not implemented. This function does handle the month and weekday names in the current locale on all platforms, however.
Please see the description of the ANSI C function strftime(3) for the syntax of the format string.
The dateDef parameter is used to fill in the fields which could not be determined from the format string. For example, if the format is "%d" (the day of the month), the month and the year are taken from dateDef. If it is not specified, Today is used as the default date.
Example of using this function:
dt = wx.DateTime() # Uninitialized datetime
bDate = "25/12/2012"
if dt.ParseFormat(bDate, "%d-%m-%Y") == -1:
# This datetime format is wrong on purpose
print "Wrong format"
elif dt.ParseFormat(bDate, "%d/%m/%Y") >= 0:
# This is correct
print "Format OK!", dt
date (string) – The string to be parsed.
format (string) – strptime()-like format string.
dateDef (wx.DateTime) – Used to fill in the date components not specified in the date string.
int
-1 if the parse failed, the number of characters parsed otherwise.
See also
ParseFormat (self, date, format)
This version of the ParseFormat method works the same, but with missing values filled in from Today.
date (string) –
format (string) –
int
ParseFormat (self, date)
This version uses “%c” as the format code, which is the same default used by Format.

int
ParseISOCombined(self, date, sep='T')¶This function parses the string containing the date and time in ISO 8601 combined format "YYYY-MM-DDTHH:MM:SS" .
The separator between the date and time parts must be equal to sep for the function to succeed.
date (string) –
sep (int) –
bool
True if the entire string was parsed successfully, False otherwise.
ParseISODate(self, date)¶This function parses the date in ISO 8601 format "YYYY-MM-DD" .
date (string) –
bool
True if the entire string was parsed successfully, False otherwise.
ParseISOTime(self, date)¶This function parses the time in ISO 8601 format "HH:MM:SS" .
date (string) –
bool
True if the entire string was parsed successfully, False otherwise.
ParseRfc822Date(self, date)¶Parses the string date looking for a date formatted according to the RFC 822 in it.
The exact description of this format may, of course, be found in the RFC (section 5), but, briefly, this is the format used in the headers of Internet email messages and one of the most common strings expressing date in this format may be something like "Sat, 18 Dec 1999 00:48:30 +0100" .
Returns None if the conversion failed, otherwise return the pointer to the character immediately following the part of the string which could be parsed. If the entire string contains only the date in RFC 822 format, the returned pointer will be pointing to a NUL character.
This function is intentionally strict, it will return an error for any string which is not RFC 822 compliant. If you need to parse date formatted in more free ways, you should use ParseDateTime or ParseDate instead.
See ParseFormat for the description of function parameters and return value.
date (string) –
int
ParseTime(self, time)¶This functions is like ParseDateTime , but only allows the time to be specified in the input string.
See ParseFormat for the description of function parameters and return value.
time (string) –
int
ResetTime(self)¶Reset time to midnight (00:00:00) without changing the date.
Set(self, day, month, year=Inv_Year, hour=0, minute=0, second=0, millisec=0)¶Sets the date and time from the parameters.
If the function parameters are invalid, e.g. month is February and day is 30, the object is left in an invalid state, i.e. IsValid method will return False.
If the specified time moment is invalid due to DST, i.e. it falls into the “missing” hour on the date on which the DST starts, a valid wx.DateTime object is still constructed but its hour component is moved forward to ensure that it corresponds to a valid moment in the local time zone. For example, in the CET time zone the DST started on 2013-03-31T02:00:00 in 2013 and so setting the object to 2:30 at this date actually sets the hour to 3, and not 2.
day (int) –
month (DateTime.Month) –
year (int) –
hour (int) –
minute (int) –
second (int) –
millisec (int) –
SetHMS(self, hour, minute=0, second=0, millisec=0)¶Sets the date to be equal to Today and the time from supplied parameters.
See the full Set overload for the remarks about DST.
hour (int) –
minute (int) –
second (int) –
millisec (int) –
SetJDN(self, jdn)¶Sets the date from the so-called Julian Day Number.
By definition, the Julian Day Number, usually abbreviated as JDN, of a particular instant is the fractional number of days since 12 hours Universal Coordinated Time (Greenwich mean noon) on January 1 of the year -4712 in the Julian proleptic calendar.
jdn (float) –
SetTimeT(self, timet)¶Constructs the object from timet value holding the number of seconds since Jan 1, 1970 UTC.
If timet is invalid, i.e.:
-1
wx.DateTime becomes invalid too, i.e. its IsValid will return False.
timet (int) –
SetTm(self, tm)¶Sets the date and time from the broken down representation in the ` wx.DateTime.Tm ` structure.
tm (wx.DateTime.Tm) –
SetCountry(country)¶Sets the country to use by default.
This setting influences the DST calculations, date formatting and other things.
country (Country) –

SetDay(self, day)¶Sets the day without changing other date components.
day (int) –
SetFromDOS(self, ddt)¶Sets the date from the date and time in DOS format.

hour (int) –
SetMillisecond(self, millisecond)¶Sets the millisecond without changing other date components.
millisecond (int) –
SetMinute(self, minute)¶Sets the minute without changing other date components.
minute (int) –
SetMonth(self, month)¶Sets the month without changing other date components.
month (DateTime.Month) –
SetSecond(self, second)¶Sets the second without changing other date components.
second (int) –
SetToCurrent(self)¶Sets the date and time of to the current values.
Same as assigning the result of wx.Now to this object.
SetToLastMonthDay(self, month=Inv_Month, year=Inv_Year)¶Sets the date to the last day in the specified month (the current one by default).
month (DateTime.Month) –
year (int) –
The reference to the modified object itself.
SetToLastWeekDay(self, weekday, month=Inv_Month, year=Inv_Year)¶The effect of calling this function is the same as of calling SetToWeekDay (-1, weekday, month, year).
The date will be set to the last weekday in the given month and year (the current ones by default). Always returns True.
weekday (DateTime.WeekDay) –
month (DateTime.Month) –
year (int) –
bool
SetToNextWeekDay(self, weekday)¶Sets the date so that it will be the first weekday following the current date.
weekday (DateTime.WeekDay) –
The reference to the modified object itself.
SetToPrevWeekDay(self, weekday)¶Sets the date so that it will be the last weekday before the current date.
weekday (DateTime.WeekDay) –
The reference to the modified object itself.
SetToWeekDay(self, weekday, n=1, month=Inv_Month, year=Inv_Year)¶Sets the date to the n-th weekday in the given month of the given year (the current month and year are used by default).
The parameter n may be either positive (counting from the beginning of the month) or negative (counting from the end of it).
For example, SetToWeekDay(wxDateTime.Wed, 2) will set the date to the second Wednesday in the current month and SetToWeekDay( wx.DateTime.Sun , -1) will set the date to the last Sunday in the current month.
Note that leaving the month or year parameters as their default values will result in the current month or year being substituted, overwriting any previous values in the wx.DateTime object.
weekday (DateTime.WeekDay) –
n (int) –
month (DateTime.Month) –
year (int) –
bool
True if the date was modified successfully, False otherwise meaning that the specified date doesn’t exist.
SetToWeekDayInSameWeek(self, weekday, flags=Monday_First)¶Adjusts the date so that it will still lie in the same week as before, but its week day will be the given one.
weekday (DateTime.WeekDay) –
flags (WeekFlags) –
The reference to the modified object itself.
SetToWeekOfYear(year, numWeek, weekday=Mon)¶Set the date to the given weekday in the week number numWeek of the given year .
The number should be in range 1-53.
Note that the returned date may be in a different year than the one passed to this function because both the week 1 and week 52 or 53 (for leap years) contain days from different years. See GetWeekOfYear for the explanation of how the year weeks are counted.
year (int) –
numWeek (int) –
weekday (DateTime.WeekDay) –
SetToYearDay(self, yday)¶Sets the date to the day number yday in the same year (i.e. unlike the other functions, this one does not use the current year).
The day number should be in the range 1-366 for the leap years and 1-365 for the other ones.
yday (int) –
The reference to the modified object itself.
SetYear(self, year)¶Sets the year without changing other date components.
